The 100m is fast but short like gamma rays, the 200m is like xrays, 400m like ultraviolet, 800m like visible light, 1500m like infrared, 5000m like microwaves and the 10,000 (or marathon if you like), is like radio waves, they travel the furthest and take the longest amount of time.

A mildly confusing analogy this could be. The 'speed' of the runner in this analogy is in fact referring to the frequency (how many wave vibrations happen each second), however all these frequencies actually travel at the same speed through space.
